August CD Rates Rise Amid Shifting Fed Outlook and Higher Inflation

With inflation and oil price spikes prompting a possible Fed hike, certificate of deposit yields now range from about 3.95% to 4.50% for various terms.

A surge in inflation and oil prices linked to the war with Iran has altered expectations for U.S. monetary policy, with the CME Group's FedWatch tool showing about a 60% chance of a rate hike at the Fed's September meeting. After three cuts in late 2025, the central bank may now pause or reverse its easing stance. Against this backdrop, banks are posting certificate of deposit rates from 3.95% for three-month terms up to 4.50% for three-year terms, offering savers a chance to secure higher fixed returns.

However, early withdrawal fees can erase earned interest, so investors should be confident they can hold the CD to maturity. Traditional savings accounts remain low at roughly 0.38% per FDIC data, prompting many to consider high-yield savings accounts, which provide variable rates comparable to top CD offers while retaining liquidity. Ultimately, consumers must weigh the higher fixed yields of CDs against the flexibility of high-yield savings accounts in a volatile rate environment.
